What are the performance differences between threads and thread pools?

What are the performance differences between threads and thread pools?

Threads are lightweight and can be created quickly, but managing many threads can lead to overhead. Thread pools, on the other hand, reuse a fixed number of threads, reducing the overhead of thread creation and destruction.

Can you explain how thread pools improve performance?

Thread pools improve performance by limiting the number of concurrent threads, which reduces context switching and resource contention. This leads to more efficient CPU usage.

Are there scenarios where using threads is better than thread pools?

Yes, for short-lived tasks or when the overhead of managing a pool outweighs its benefits, using individual threads can be more efficient.

What are some common use cases for thread pools?

Common use cases for thread pools include handling web server requests, processing background tasks, and managing concurrent database connections.
